A new lower bound on the smallest eigenvalue Ο (A B) for the Fan product of two nonsingular M-matrices A and B is given. Meanwhile, we also obtain a new upper bound on the spectral radius Ο(A β’ B) for nonnegative matrices A and B. These bounds improve some results of Huang (2008) [R. Huang, Some ine
